Transversely of the frame 13, I mount a shaft from over which as thebelt 15 goes therearound, 19 having a driving pulley 20 on one end and athe waste drops into any suitable receptacle such disc 21 on the otherend. The disc 21 is provided as a drum 40. Since the belt 10 is movingaway '45 w th a p u a y of h s 22 sp d at vari us from the discharge endof the washing machine radial distances from the disc center, and in oneconveyor 39, the waste falling from the conveyor 0f t e 110168.depending 1113011 the throw d s ed; strings therefrom to touch the beltbefore leav- I fi a p 23 which ably carries the ends ing the conveyorand thus the belt carries the of the connecting rods 24 and 25.

carries the belt drum 11, the gear being fixed As the belt 10 is movedby the ratchet action 35 on the shaft. A pawl 49 rockably carried beofthe rod 24 working the plates 26 and 2'7 to and fro to revolve the gear28 by the pawl 49, the waste thereon is given a jerky motion. The wastecomesfrom out of a bath of lubricating oil in the Washing machine 38,and as it is jerked along intermittently on the belt, the oil carried bythe waste may drain down through the belt 10 to be caught in the pan l4and drained back to the machine 38 by the trough 41 and pipe 42. The oilcontinues to be drained from the waste as it returns on the lower belt15.

The waste having been thoroughly saturated and deposited upon the belt10 with an excess of lubricating oil from the machine 38 and the amountof oil desired to be left in the waste being known, the rate of travelof the belts 10 and 15 is adjusted from the shaft 19 by varying theposition of the pin 23 on the disc 21 and also by shifting the outerends of the rods 24 and 25 up and down between the respective plates 26,27 and 31, 32 which variations will accordingly effect thecircumferential travel of the gears 28 and 33 by their respective pawls,whereby, by the time the waste is dumped from the belt 15 into the drum40, the waste has been drained to have just the correct amount of oilcontent remaining, which content is checked from time to time.

The lower oil pan l8 drains into any suitable receptacle, such as thedrum 43, from which the oil may be returned to the machine 38. The belts10 and 15 are preferably enclosed by a metal housing 44 to retain auniform temperature within. The oil in the machine 38 is maintained at arelativelyhigh temperature, and it is desirable to retain the heat ofthe oil while the waste is carried by the belts 10 and 15 so as topermit proper draining of the oil therefrom.

From the foregoing description, it is thus to be seen that wasteinitially saturated and dripping with oil is carried for an appreciabletime interval on draining belts without being passed through wringers orcentrifugal machines, and that by controlling the time interval, thewaste may be brought to have any desired oil content by the time it isdumped from'the belts. By dumping the waste from the draining belt atthe end of the predetermined time interval the waste is then slightlycompressed and also surrounded by an imperforate wall so that furtherseparation of the oil from the waste is arrested and the waste is heldready for use in a loosened fluffy condition free from any matted orfelted condition as was encountered heretofore in using centrifuges orthe customary wringer rolls.

While I have herein shown and described the device as having two belts10 and 15, it is entirely possible to employ'but one belt 10, pro vidingthere is sufiicient room to extend its length in order to handle thewaste as fast as it may be dumped on the belt from the machine 38, andit is obvious that other variations in the structure may be made withoutdeparting from the spirit of the invention, and I, therefore, do notdesire to be limited to the precise form as shown and described, nor anymore than may be required by the following claims.

I claim:

1. That method in the reclaiming of used journal box waste in acontinuous operating system which comprises lifting the Waste from abath of hot oil, suspending the waste in small masses in relatively thinlayers to permit the oil to drain therefrom by gravity, moving thesuspended waste along away from the bath while draining for a definitetime interval which is correlated with the rate of draining of the oilto obtain a definite residual oil content in the waste, and dumping thewaste into a mass to prevent further separation of the oil therefrom.

2. In the art of journal box waste reclamation, the step of suspendingheated oil saturated waste spread outtin a relatively thin layer for adefinite time interval to allow the oil to drain therefrom by gravity toleave adefinite amount of oil in the waste as predetermined for finallubricating use, and the step of placing the waste in a mass followingsaid time interval to prevent further removal of oil, whereby the wasteis maintained in a fluffy'loosenedv condition ready for use in repackingjournal boxes.

3. In the art of reclaiming used journal box waste, the step of liftingwashed waste from a bath of hot oil, the step of continuously suspendingand spreading out the waste in an oil saturated condition as rapidly astaken from the bath in substantially a uniform, relatively thin layer toallow the oil to drain therefrom by gravity; the step of maintaining thesuspension of the waste for a definite time interval which is correlatedwith the thickness of the waste layer and the temperature ofthe'wasteand oil; and the step of arresting further draining of the oilfrom the waste at the end of said interval, said waste being maintainedin a heated condition while suspended to preserve a known oil contenttemperature. I

4. In means to provide journal box waste with a definite degree oflubricating oil saturation, the combination of a tank in which the wasteis thoroughly saturated with lubricating oil, a perforated belt adaptedto receive the saturated waste from the tank, and a closed wallreceptacle at the discharge end of the belt, said belt being movedtoward the receptacle at a speed dependent upon the residual oil contentdesired in said waste so as to permit excess oil only to drain fromthewaste before reachingsaid receptacle, and said'waste being dumpedfrom the belt into said receptacle to prevent further draining of theoil therefrom.
